Introduction
The human heart is typically divided into four chambers: the left ventricle, left atrium, right ventricle, and right atrium. In healthy adult males, the normal diameter of the right ventricular outflow tract (RVOT) ranges from 21 to 23 mm; in healthy adult females, it ranges from 23 to 26 mm. If the RVOT diameter exceeds these normal limits, pulmonary arterial hypertension may be a potential underlying cause.

The heart is one of the most vital organs in the human body. In a healthy individual, the heart typically consists of two atria and two ventricles. The right ventricle lies at the most anterior (front) portion of the heart. Abnormal narrowing or widening of the right ventricular outflow tract (RVOT) can adversely affect cardiac function and lead to heart disease. So, what constitutes the normal measurement for the RVOT?

Normal Values for the Right Ventricular Outflow Tract (RVOT)

The human heart is anatomically divided into four chambers: the left ventricle, left atrium, right ventricle, and right atrium. In males, the normal RVOT diameter ranges from 21 mm to 23 mm; in females, it typically measures between 23 mm and 26 mm. An RVOT measurement exceeding the upper limit of normal may indicate pulmonary arterial hypertension, whereas a value below the lower limit often suggests RVOT stenosis.

If you experience noticeable discomfort in the chest area, seek prompt medical evaluation at a hospital. Diagnostic tools such as echocardiography (ultrasound of the heart) or electrocardiography (ECG) are commonly used to assess cardiac structure and function. If RVOT stenosis is diagnosed, pharmacological treatment—under physician supervision—may be initiated, including medications such as rosuvastatin, lovastatin, and aspirin. In severe cases, surgical intervention may be required.

It is advisable to maintain stable emotional well-being, avoid excessive physical exertion, and adhere to a light, balanced diet—minimizing intake of high-cholesterol and high-fat foods. We hope this information proves helpful to you.
